Generalised method of moments gmm

WebAbstract. For many inference problems in statistics and econometrics, the unknown parameter is identified by a set of moment conditions. A generic method of solving moment conditions is the Generalized Method of Moments (GMM). However, classical GMM estimation is potentially very sensitive to outliers. Robustified GMM estimators … WebGeneralized Method of Moments 1.1 Introduction This chapter describes generalized method of moments (GMM) estima-tion for linear and non-linear models with …
